Question about examples/configs/flash_sd3.yaml

[Isalia20]

In the exampels/configs/flash_sd3.yaml file there is sampling scheduler called FlashFlowMatchEulerDiscreteScheduler which is imported from diffusers in flash_diffusion/examples/train_flash_sd3.py. I couldn't find this class in diffusers in the latest version, so it would be great if you could clarify where to find this class
